The Walmart Batteries are 8.82/18 which is also 49 cents. So both batteries are the same price, you should buy the better quality battery in this situation.

If x^2 - 6xy = z - 9y^2, make x the subject of the formula

alukav5142 [94]

$~~~~x^2-6xy=z-9y^2\\\\\implies x^2- 2\cdot x\cdot 3y + (3y)^2 - (3y)^2 = z-9y^2\\ \\\implies (x-3y)^2 -9y^2 = z-9y^2\\\\\implies (x-3y)^2 = z\\\\\implies x - 3y =\pm\sqrt z\\\\\implies x = 3y\pm\sqrt z$
